Topic: Smooshing and Plowing

I can't get my Orbot Hadron to print anything nicely?
Here are clear ABS prints ET 200 BT 85
Repetier 070

Looks like I have z axis calibration problem this is using 2760 steps/mm
done by calibration

Any suggestions

Top of peg seems to get smooshed

Re: Smooshing and Plowing

Backlash in Z can cause the first couple of layers to be shorter than they are supposed to be.  I would think that it looks like they are over extruded, except that the there are gaps between the threads.  If flow was too high, the threads would be touching.

The peg looks like the problem might be cooling.  Everything is getting shoved around because it is still hot and soft when the next layer goes on.  Set the minimum layer time in cool settings to something like 10.

Re: Smooshing and Plowing

I have very limited experience with these things but is the tip of the extruder actually digging up the layer as it moves across it?

Re: Smooshing and Plowing

Yes it looks like to me that the nozzle is plowing up the ABS

Z axis screwed up or not moving up/down correctly orr backlash

Looks like it is happening on the bed (bottom of cup)
and 10mm up (top of peg)
